Hi Serkan,
Thanks for getting back.
I found the problem and its fixed now. My site is on Cloudflare and it appears that a Cloudflare feature called ‘Rocket Loader’ was the one interfering with the smooth scroll effect.
I switched it off and everything is back to normal now.
I hear the Rocket Loader is known to cause conflicts with many themes and plugins, I dont know if you guys would want to check on how to fix it.

Thanks.
